Frequently Asked Questions - HC-750Y Vevor

Why won't my mill start?

First check if the indicator light is on. If it does not turn on, check the outlet and power cord. If the light is on, make sure the lid is tightly closed and the induction switches are correctly triggered. If the problem persists, press the overload protector or replace the carbon brushes.

What if the mill stops suddenly?

This may be due to blade blockage, overload, or worn carbon brushes. Unplug the appliance, clean the bottom of the tank, reinstall the carbon brushes if necessary, then press the overload protection button to restart.

Why is the motor getting very hot?

Slight heating is normal, but overheating may be caused by wet materials, too long grinding time (observe 3 min work for 5-10 min rest), or excessive material quantity (do not exceed 2/3 of the tank). If the motor stops, reinstall the carbon brushes and press the overload protector.

How to clean the mill properly?

Always unplug the appliance before cleaning. Removable parts (tank, blade) should be hand washed with warm water, without abrasives. Never immerse the motor block in water: use a damp cloth to clean it. Dry all parts thoroughly before reassembling.

How long should I grind?

It depends on the material: spices 20-30 seconds, cereals 30-60 seconds, hard materials 1-2 minutes. For oily materials, grind in 10-second intervals with pauses. Do not exceed 3 minutes of continuous operation.

Can I grind wet foods?

No, the mill is designed only for dry materials. Wet foods or those containing water may damage the motor and cause overheating. Always dry your ingredients before grinding.

How to replace the carbon brushes?

After prolonged use, the carbon brushes wear out. Unplug the appliance, remove the old brushes from each side of the motor and install new ones. Ensure they are securely in place. A set of spare brushes is included with the mill.

Why are there sparks?

Sparks on the carbon brush surface are normal during initial use due to break-in. If they persist, clean the brush surface with a dry cloth. The friction smell disappears after a few uses.

How to use the overload protector?

In case of overload or blade blockage, the overload protector automatically cuts off power. To reset, unplug the appliance, remove the cause of the blockage, then press the protection button (often a small red button) before reconnecting.

What materials can I grind?

The mill is suitable for: cereals (wheat, rice, corn), spices (pepper, cinnamon, cumin), herbs, medicinal plants (ginseng, astragalus), coffee beans, granulated sugar, etc. Avoid highly fibrous materials (like loose tea) that create fluff, and grind intermittently.

If any parts, the power cord, or the grinder are damaged, call the Customer Service number shown in this manual.

1. Always unplug the power cord from the outlet when not in use, before putting on or taking off parts or accessories, and before cleaning. After unplugging the unit, turn the power switch ON, then OFF to ensure that all power has been discharged from the grinder.
2. This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
3. NEVER LEAVE THE GRINDER UNATTENDED WHILE IT IS RUNNING!
4. Wait until all moving parts have stopped and turn off the power before removing any part from the grinder.
5. DO NOT use outdoors; this product is intended for INDOOR USE only.
6. DO NOT pull the power cord to disconnect.
7. DO NOT USE WITH AN EXTENSION CORD. Always plug directly into a grounded wall receptacle.
8. This grinder uses a grounded, three-prong plug (hot, neutral and ground). The grounding plug is used for electrical appliances with a metal shell to prevent electric shock. DO NOT change or alter the plug in any way. NEVER break off a grounding prong from a 3-conductor plug. Doing so will invalidate the warranty and may cause electric shock.
9. Place the grinder on a firm and stable surface. Ensure that the grinder is not placed near the edge of the worktop, where it can be easily pushed off or fall.
10. The Gear Housing and the Motor Cover may become HOT during operation. This is normal. DO NOT TOUCH these parts while operating.
11. To reduce the risk of unintentional starting, check that the control is OFF before plugging the cord into wall outlet. To disconnect, turn the controller to OFF, then remove plug from wall outlet.
12. DO NOT operate your grinder under a wall cabinet. Always unplug the unit from the electrical outlet when storing

it. Not doing so could create a risk of fire, especially if the appliance touches

the walls of the garage or the door touches the unit as it closes.

1. NEVER plug the grinder in where water may flood the area.
2. To protect against risk of electrical shock, DO NOT submerge the grinder in water or other liquids. Be sure the grinder is disconnected from the power source before cleaning. NEVER rinse the Grinder Motor under running water, only use a moist cloth to clean the Grinder Motor Unit.
3. The use of attachments or parts not specifically recommended or sold by the manufacturer for this grinder will void the warranty and may cause fire, electric shock or injury.
4. HANDS WASH ALL PARTS! DO NOT USE DISHWASHER. Never put the unit near a hot burner, in an oven, or in a dishwasher.
5. NEVER use abrasive cleaning agents or abrasive cloths when cleaning the grinder.
6. The Manufacturer disclaims any responsibility in the case of improper use of Grinder. Improper use of the Grinder voids the warranty.
7. DO NOT REMOVE WARNING LABELS FROM THE GRINDER. Doing so will void the product warranty and may result in serious personal
8. This appliance must be grounded while in use to protect the operation from electrical shock. This grinder uses a grounded, three prong plug should be connected directly to a grounded 120V(US)/230V(EC), three prong grounded wall outlet receptacle. Grounded plugs are used on metal-encased electric appliances in order to provide protection from a electric shock. DO NOT change or alter the plug in anyway. NEVER off a grounding prong from a 3-conductor plug. Doing so voids the warranty and may result in electric shock.
9. Type X attachment: If the supply cord is damaged, it must be rep by a special cord or assembly available from the manufacturer or its service agent.

24. Do not fill the grinding tank to full, otherwise it will cause overload. The material you are going to grind at one time must cover the long blade in the middle and no more than 2/3 of the tank. Because this machine needs space to complete the cycle of the blades and the material to be ground. 25. Even if grinding stone, it only takes 2 minutes, so don't use it for

long. It takes 5-10 minutes to rest after every 3 minutes of work. If grinding some hard items, there should be an interval to prevent bearing overheating and damage to the motor. General grains only need to be ground into powder. If you are not satisfied with the grinding, you can sieve out the coarse particles with a mesh screen and grind again for finer powder.

1. To ensure safety, the nut should be tightened before grinding. After long-term use, blades and carbon brushes need to be replaced if they are worn.
2. The motor of the grinder is a brush motor. Sparks are normal during the first several uses. The sparks and the brush friction odor will disappear after you use the machine some times later.

You can grind some rice or tea leaves first for several times to eliminate the odor.

PRODUCT STRUCTURE

1. Operations Guide:

1) Open the upper cover and put the dried material inside; 2) Close the upper cover tightly; (Please make sure the lid is rotated to the end and locked tightly on the top.) 3) Plug in and turn on the timer switch, then turn on the switch for grinding (rolling sound will be heard); 4) Turn off the switch; (When you hear the sound rolling evenly, the material has been ground into powder, then you can turn off the switch.) 5) Disconnect power supply before opening; 6) Open the upper cover and brush the powder out.

2. Grinding Cautions:

Wet or water-containing materials cannot be ground; dry materials only. Grinding time varies depending on the type of material used, and different types of materials require different grinding methods for better results.

1) Before using the grinder for the first time, put some rice and dry leaves to grind for about 30 seconds to clean the inner wall and remove stains.

2) For seasonings, it is generally recommended to grind for about 20 seconds and do not grind for too long. (Chili, Pepper, Fennel, etc.)

3) For ordinary grains, it is recommended to set the timer for about 3 seconds; if the desired effect is not achieved, grind again. (Soybeans, Millet, Black rice, Corn, etc.)

4) For general materials, it is recommended to set the timer for about 2 minutes. (Ginseng, Astragalus, Asparagus, etc.)

5) For greasy materials, it is recommended to first dry and de-oil the materials, and then grind them intermittently. Grind for about 10 seconds and pause 5 seconds. Check the grinding effect during the process to avoid the machine getting overheated, causing the materials to become burnt. (Sesame, Peanuts, Walnuts, etc.)

6) For super hard materials, it is recommended to first break the material into small pieces and then grind them. Pause for 10 seconds after grinding for about 1 minute. The grinding can be completed after about 2-3 minutes (e.g., crystal sugar, cumin, cinnamon).

7) For fibrous materials, the material itself has a fibrous structure, so instead of being ground into powder, it will appear fluffy. It is recommended to grind these materials intermittently (e.g., barley, Ganoderma lucidum).

Notice: When you first use the machine, you'd better clean the machine with a cloth moistened with vinegar or medical alcohol, and then put some rice and dried tea leaves into the grinding bin, grind them for 30-50 seconds, then pour the powder out and clean the grinding bin.

3. Common Questions:

*Why can't the grinder be started?

First check whether the indicator light is on.

If the indicator light is not on, check whether the power plug is inserted tightly and whether the power cord is damaged (you can replace the power cord with that of other household appliances).

If the indicator light is on, the possible reason is that the induction switch of the two buckles of the cover is not triggered yet.

*What to do if the grinder suddenly stops working?

If the grinder stops working, the reason may be that the blades are stuck, or the overload protector function works because of overload, or the carbon brush is worn. It's easy to solve this problem.

You just need to clean the blades' bottom or re-install the carbon brushes on both sides again, and then press the overload protector button again. The grinder could work well. Please see the overload protector and carbon brush in the attached pictures, please check that.

*Why does the motor become hot?

It is normal for the grinding machine to be slightly hot, because the working principle of the machine is to pulverize the material into powder through the high-speed rotation of the blades. The whole process is carried out in the closed grinding bin, which will generate heat and cause the machine to heat up.

There may be several reasons for machine overheating:

1) The materials ground are wet, with moisture.

Please dry the materials as much as possible before grinding, and then grind them when they are completely cool.

2) Grinding time is too long.

The machine must take 5-10 minutes to rest after every 3 minutes of use. If you are grinding some hard items, there should be an interval to prevent bearing overheating and damage to the motor.

prevent bearing overheating, damage to the motor.

3) Put too much material into the grinding bin at one time.

The material you are going to grind at one time must cover the middle of the long blade and no more than 2/3 of the tank. Because this machine needs space to complete the cycle of the blades and the material to be ground. If the machine overheats and stops working, you can also solve it by re-installing the carbon brushes on both sides again and then pressing the overload protector button again, then the grinder could work well.

INSTRUCTIONS OF AIR OVERLOAD PROTECTOR

When blades are jammed in the grinding bin, it will happen that the air overload protector pops up and the machine automatically cuts off the power supply. If this situation happens, turn off the power and check the grinding bin. Just need to clean the blades bottom and press the overload protector button again, then the grinder could work well.

* Upright type grinder:

*Swing type grinder:

HOW TO CLEAN UP THE GRINDING BIN

You can clean up the grinding bin of the grinder with a brush first, and then clean it with a dry cloth.

After using blades for a long time, you can remove them and clean with water. (The blades of a new grinder must be very tight; you need to use it for a long time, then blades can be removed.)

• Firstly, loosen the nut by using a pincer and remove the blade. • Secondly, wipe the grinding bin with a dry rag after removal of the blade, and please do not clean with water directly.

Please Note: If you clean the blades by using a wet rag or with water directly, please make sure the grinding bin and the blades are dry enough before re-installing the blades.

- Lastly, install the blades and tighten the nut, and it is finished.
